Please do not adjust your dosage unless the doc/pharmacist specifically instructs you to do so.

Oral Chlorpheniramine Dosage for Adults
Depending on the particular product, a typical chlorpheniramine dose for adults is 4 mg every 4 to 6 hours (not to exceed 24 mg per day) for immediate-release products or 8 to 12 mg every 8 to 12 hours (not to exceed 24 mg in 24 hours) for various extended-release products. Keep in mind that these are general guidelines and specific medications may have different directions. Be sure to follow the directions for your particular product.

Older adults, who may be more sensitive to chlorpheniramine side effects, may need a lower or less frequent dosage.
